SHUTTLE.l

Application led April 5, 1923. Serial N0. 6303050.

rlhis invention relates to shuttles for use in connection with looms .and provides a construction `whereby the shuttle may be replenished at either end-of the shed as may be desired, whereby the bobbin or cop holding means is so constructed that it cannot be forced out of its properv position relative to the shuttle during the removal of the empty bobbin or its replacement by a filled bobbin, and which avoids liability of the yarn being caught thereon. Byperinitting the shuttle to be replenished at either end, the yarn on the bobbin or cop may be more completely utilized, since it is not necessary to replenish the shuttle until less than sufcient yarn for a single. pick instead of for two picks is left.

For a more complete understanding of this invention reference may be had to the accompanying drawings, in which Figure l is a plan view of the shuttle.

Figure 2 is a longitudinal section on line 2 2 of Figure l.

Figure 3 is a perspective of a bobbin or cop-holding bar.

The shuttle proper is indicated by the numeral 1 and has at each end a yarn eye 2 of any suitable construction. Between the yarn eyes the shuttle is slotted as at 3 forming the mortise to receive the bobbin or cop (not shown). In order to retain the bobbin or cop in position within this mortise, holding members each comprising a bar 5 constructed as shown in detail in Figure 3 may be employed. At each end of the bar 5 is a perforation 6 for the reception of a bolt 7' which passes through the body of the shuttle and through a yarn eye, this bolt serving to secure the bars and the eyes in position within the body of the shuttle. The bars 5 are spaced apart between the yarn eyes to form a space for the reception of the bobbin or cop and closely adjacent each yarn eye they are brought somewhat together, as shown at 8, the portions 8 being provided with a series of parallel grooves 9 therein of the usual construction for gripping engagement with the spring rings commonly employed about the butts of the bobbins or cops. The. sides of the mortise are provided with grooves to receive and house the intermediate portions of the bars as they are sprung apart by the insertion of the bobbin bearing between them at the portions 8.

From this description it will be seen that the bobbin or cop may be placed in position with its pointed end extending toward either of the eyes 2, the butt end engaging between the portions 8 adjacent the opposite ends of the bars 5. As these bars are held in position by abolt 7 at opposite ends they can not be swung about either one of thesel bolts 'out of position between they sides of the shuttle as might -be the case. where they are attached at one end only.- Furthermore asthey extend the entire length of the bobbin there is no danger of the yarn becoming caught thereon, since there are no projecting ends offering obstruction to the free passage of the yarn. Moreover as the cop or bobbin may face in either direction the shuttle may be replenished at either end of the shed.

Having thus described an embodiment of this invention it should be evident to those skilled in the art that many changes and modifications might be made therein without Ideparting from its spirit or scope as defined by the appended claims in which the word bobbin has been used generically to denote any thread carrier used in connection with shuttles.

I claim z- 1. A shuttle havingv a bobbin-receiving mortise, and bobbin-retaining means extending the length of the mortise, said means having bobbin-gripping portions adjacent both ends, with middle portions therebetween, said bobbin-gripping portions being offset inwardly relatively to said middle portions.

2. A shuttle having a bobbin-receiving mortise, and bobbin-retaining means comprising a pair of resilient bars extending throughout the length of the bobbin on opposite sides thereof within said mortise and secured to the shuttle. f

3. A shuttle having a bobbin-receiving mortise, and bobbin-retaining means comprising a pair of bars extending throughout the length of the bobbin Ion opposite sides thereof within said mortise, and form-ed to receive and hold a bobbin therebetween pointing in either direction longitudinally of the shuttle.

l. A shuttle having a bobbin-receiving mortise, a yarn eye at each end, and a bobbin-gripping member' extending between said eyes within said mortise having portions adjacentk both ends Vfor gripping engagement with the butt of a bobbin inserted within said mortise with its pointed endV extending toward either of said eyes.

5. A shuttle having a bobbin-receiving mortise, a yarn eye at each end, and a bob-- bin-gripping member extending between said eyes Within said m'ortise and made fast at its ends thereto, said member having portions adjacent both ends for gripping the butt of a bobbin pointed in either direction.

6. A shuttle having a bobbin-receiving mortise, a yarn eye at each end of said shuttle, and means extending from `one eye to the other for holding a bobbin Within said mortise with its pointed end extending tof Ward either eye, said means heing secured at both ends thereof to the shuttle.

7. Al shuttle having a yarn eye at each end and having a longitudinal mortise therein between said eyes to receive a bobbin, and a bar extending along each side of said mortise and fastened to said eyes7 said bars be- 20 ing formed to engage a bobbin placed there between and pointed toward either of said eyes.

8. A shuttle having a mortise, a pair of bars extending longitudinally of said inortise and formed to be sprung apart by a bobbin engaging therebetween, said shuttle having grooves in opposite Walls of the mortise to receive and house said bars when the bobbin is placed in position.

9. A shuttle having a bobbin-receiving mortise, a yarn eye at each end of said shuttle, a'pair of bars spaced apart Within said mortise to retain a bobbin therein, and a fastener extending through each of said eyes and bars for fixing said eyes and hars to said shuttle. Y f

In testimony whereof I have aflixed my signature. i
